7. EXPANSION VALVE For direct expansion units, select an expansion valve in accordance with capacity data and as required by

expansion valve manufacturer. Expansion valves with external equalizers should be used. After the temperature has reached design conditions, adjust the expansion valve to obtain 8 to 10º F superheat at the suction line. Expansion valves are to be installed in accordance with the specific manufacturer’s

recommendations. Units that require an external equalized expansion valve must have that line connected. Proper location of the bulb is extremely important to the performance of the coil. Good thermal contact to the suction line is also essential. On solder type valves, a wet cloth wrapped around the valve during installation will protect it from overheating and damage. On multiple evaporator systems, the piping should be arranged

such that the flow from any valve cannot affect the bulb of another.

8. DRAIN LINE The drain line must be pitched to effectively drain condensate. All drain lines subject to freezing temperatures

must have drain line heaters and be insulated. Drain line traps must also be heated to prevent freezing up of the drain line and trap.

The cleaning of the finned heat exchanger is of the upmost importance to ensure smooth operation and long life of the equipment.

- There is no general rule how often it should be cleaned. Frequency and method of cleaning depend on

the customer and must be determined by the customer´s operating personnel. If need be, ice must be defrosted with a hot air drier or hot water.

- The equipment is always supplied in a clean condition. If, during installation and/or first operation hours, contamination reaches a state where capacity can be affected, it is necessary that the unit is cleaned before operation.

- When cleaning the unit it must be out of operation and all electrical power disconnected. Mechanical Cleaning of the Heat Exchanger

- Blow down the fins with air (only suitable for light, dry and dusty deposits). - Cleaning with compressed air (maximum pressure 6 bar, minimum distance from fins – 8 inches).

- If some contamination is located mainly at the inlet of the fins, clean with a soft brush or use an

- For oil containing deposits, it is acceptable to add detergent to the water. Make sure not to deform the

fins. - When using chemical substances, make sure they do not corrode the heat exchanger material and casing. Rinse the heat exchanger and casing after treatment.

- When cleaning with liquid or compressed air, the fans must be switched off. Do not spray them directly.

- Clean the coil from top to bottom in order to allow the contamination to drain downwards. Cleaning must be continued until all contamination has been removed.

- Always clean/spray in the direction of the fins. Never clean at 90° to the fins!

- Maximum allowed vapor pressure is 6 bar. Maximum allowed water pressure before the outlet is 80 to 100 bar.
